Pindao Came from the Eastern Tang Dynasty

Li Qingxuan, a Taoist priest from Baiyunguan in Chang'an, walked out of the Hexi Corridor with half of the Tao Te Ching and the art of investigating objects. Seeing that the rituals and laws of the countries in the Western Regions were in chaos and that the Turkic tribes were not yet civilized, he used the canons of the Tang Dynasty as his bones and the various schools of thought as his flesh. He set up an altar in the quicksand to lecture, and he analyzed rituals and music in a felt tent. From the debates on Buddhism and Taoism in the ancient city of Gaochang, to the calendar disputes in Tubo, from the arithmetic exchanges between Persian merchants, to the innovation of writing on the Fusang Islands, he integrated the elegance of the Tang Dynasty into the foreign soil and water with the Taoist heart of "harmony with light and dust". Along the way west, there are dangers of swords and swords, and sparks of collision of civilizations, eventually becoming a cultural legend that spans thousands of miles.
